CVE-2018-6480 : What You Need to Know

CCN-lite 2 has encountered a type confusion issue leading to memory access violations and failure of the nonce feature, affecting loop prevention mechanisms.

Understanding CVE-2018-6480

CCN-lite 2 faces a critical vulnerability due to type confusion, impacting memory access and the effectiveness of the nonce feature.

What is CVE-2018-6480?

The issue stems from an incorrect assumption in ccnl_fwd_handleInterest regarding the union member 's' type, affecting the nonce feature's functionality.
If 's' is of type struct ccnl_pktdetail_ccntlv_s or struct ccnl_pktdetail_iottlv_s, the code referencing the local variable nonce becomes ineffective.

The Impact of CVE-2018-6480

Memory access violations can lead to system instability and potential exploitation by attackers.
